Coloradoâs Scenic Million Dollar Highway: Silverton to Ouray. The scenic drive on Coloradoâs Million Dollar Highway (U.S. Route 550), from Silverton to Ouray, just might be the most eye-popping, awe-inspiring drive we have ever taken.
Workers were laid off. Silverton took the full weight of a huge rock slide that resulted in an unprecedented closure of U.S. 550 over Red Mountain Pass. It began Jan. 12, when a Super Bowl-field-sized slab of mountainside began slipping and huge hunks of quartzite fell onto the road known as the Million Dollar Highway.
